At a glance
- Fat grafting (fat transfer) uses your own fat, harvested by liposuction, to add volume elsewhere.
- Common uses include the face, breasts, hands and body contouring.
- Because it is your own tissue, results can look and feel natural.
- Some of the transferred fat is reabsorbed, so results are somewhat unpredictable.
What fat grafting is
Fat grafting, also called fat transfer or lipofilling, is a procedure that takes a person’s own fat from one part of the body and moves it to another to add volume or improve contour. Fat is gently removed from an area with excess (such as the abdomen or thighs) using liposuction, processed to concentrate the usable fat cells, and then injected in small amounts into the target area. Using your own tissue avoids implants and can improve contour in both the donor and recipient sites. Because the material is living tissue rather than a synthetic filler, the fat that survives becomes a natural, integrated part of the treated area.
Common uses
Facial fat grafting restores volume lost with ageing — cheeks, temples, tear troughs and lips — for a softer, fuller look, and it can help smooth hollows and improve overall facial balance. It is often combined with other procedures such as a facelift, which lifts and repositions tissue while fat transfer replaces lost volume. Beyond the face, fat grafting is used to rejuvenate ageing hands, which can look thin and bony over time, and to correct contour irregularities left by injury, previous surgery or other liposuction. It is also used for modest breast enhancement and, importantly, in reconstruction — for example to refine shape and soften contour after breast surgery. In these settings the aim is a gradual, natural-looking improvement rather than a dramatic change in size.
Who might consider it, and who is suitable
A suitable candidate is generally in good general health, does not smoke or is willing to stop, and has realistic expectations about what the procedure can and cannot achieve. Because fat has to be harvested before it can be transferred, there needs to be enough donor fat available; very lean people may have limited reserves. People who understand that some fat will be reabsorbed, that the final result takes time to settle, and that more than one session may be needed tend to be the most satisfied. As with any elective surgery, certain health conditions or medications may make the procedure less advisable, which is why a proper assessment matters. A consultation with an accredited plastic surgeon is the right place to discuss goals, review your medical history and decide whether fat grafting suits you.
How it is done
The procedure has three broad stages: harvesting, processing and injecting. First, fat is harvested from a donor area through small liposuction openings. The fat is then processed — for instance by allowing fluid to separate out — so that a concentrated, usable portion remains. Finally, the surgeon injects the fat in many small amounts through fine passes, layering it so that each parcel of fat sits close to a blood supply that can nourish it. Placing fat gradually and in small quantities, rather than in large pockets, gives it the best chance of establishing itself. Depending on how much work is planned, the procedure may be carried out under local anaesthesia with sedation or under general anaesthesia.
Preparation
Preparation begins with an honest consultation covering your goals, medical history, medications and any previous surgery. Your surgeon may ask you to stop smoking well beforehand, as smoking impairs healing and reduces how much fat survives, and to pause certain medicines or supplements that can increase bleeding, following their specific advice. You will be told when to stop eating and drinking before a procedure involving sedation or general anaesthesia, and it is sensible to arrange time off and someone to help you home afterwards. This is also the moment to raise questions about what results are realistic, the possibility of a second session, and the recovery you should expect.
Recovery
Recovery involves both the donor site, where fat was taken, and the treated site, where it was placed. Expect swelling and bruising at both, which are usually most noticeable in the first days and then ease over the following weeks. The donor area may feel tender or firm for a time, much as it would after liposuction, and a compression garment is sometimes advised. Most people take a short period away from work and strenuous activity, returning gradually as comfort allows. Because swelling can exaggerate the initial result, the treated area often looks fuller at first than it eventually will. Following your surgeon’s aftercare advice — on activity, positioning and wound care — supports smooth healing.
An important point about results
A key feature of fat grafting is that not all of the transferred fat survives. Some of the injected fat is reabsorbed by the body, which makes the final volume somewhat unpredictable and is why surgeons often slightly overfill to allow for the portion that does not take. The final result appears only once swelling settles over the following months, and occasionally a second session is needed to top up or refine the outcome. The fat that does survive generally lasts long term, giving durable, natural volume. How much fat “takes” depends on technique, the area treated and individual healing, which is why gentle harvesting and careful placement matter so much and why results vary from person to person.
Risks and complications
As with any surgery, fat grafting carries risks. These include bleeding, infection, and contour irregularities such as asymmetry or an uneven surface. Transferred fat can sometimes form lumps, firm areas or oil cysts, and a portion of the fat may simply not survive, leaving less volume than hoped. There are also the general risks of anaesthesia and, rarely, more serious complications. In breast fat grafting it is particularly important that any lumps are assessed appropriately, so that changes related to the grafting are not confused with other breast changes that need separate evaluation. Choosing an experienced surgeon and following aftercare instructions help reduce these risks, but no procedure is entirely without them, and it is important to weigh them honestly against the expected benefit.
Advantages and limitations
The main advantage of fat grafting is that it uses your own tissue, so the result can look and feel natural and, in some cases, avoids the need for an implant. Taking fat from an area of excess may also improve the contour of the donor site. The limitations are equally real: the amount of volume that can be added in one session is bounded by how much fat survives, the outcome is partly unpredictable, and more than one procedure may be required to reach the desired result. For a large or very defined change, an implant-based approach may achieve more in a single step. Understanding this balance — natural material and dual benefit on one side, unpredictability and the possible need for repeat sessions on the other — helps set expectations that the procedure can realistically meet.
Choosing a qualified provider safely
Choose an accredited plastic surgeon experienced in fat grafting, operating in a licensed facility, as careful harvesting and gentle placement strongly influence how much fat survives and how smooth the result is. During the consultation, ask about the surgeon’s training and accreditation, where the procedure will be carried out, what anaesthesia will be used and who will provide it, and how complications would be managed. A trustworthy provider will discuss both benefits and limitations openly, avoid pressuring you, and be candid about the chance of needing a second session.

When to seek medical attention after
Some swelling, bruising and tenderness are expected after fat grafting. However, contact your surgeon or seek medical attention promptly if you notice increasing or severe pain, bleeding that does not settle, spreading redness or warmth around a wound, discharge, or a fever. These can be signs of a complication such as infection that needs assessment. If you develop sudden breathlessness, chest pain or another symptom that feels serious, treat it as an emergency. Knowing the warning signs in advance, and having a clear point of contact with your surgical team, means any problem can be dealt with early.
Common questions
Is fat grafting permanent?
The fat that survives is generally long-lasting, though some of what is injected is reabsorbed, so results are partly unpredictable.
How much fat survives?
It varies with technique and site; surgeons often slightly overfill to allow for the portion that is reabsorbed.
Where does the fat come from?
From an area of excess such as the abdomen or thighs, removed by liposuction.
